Spinocerebellar ataxia


Overview

Spinocerebellar ataxia (SCA) is a group of inherited conditions that are characterized by degenerative changes of the nervous system (brain and spinal cord).[1] There are many different types of SCA; the signs and symptoms vary by type but may include an uncoordinated walk (gait), poor hand-eye coordination, and abnormal speech (dysarthria).[2][3] Depending on the type, SCA can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. Treatment is supportive and based on the signs and symptoms present in each person.[3]
